No significant difference in MALAT1 expression was noted among patients classified into the different subtypes of T and NK lymphomas: extranodal NK/T cell lymphoma of nasal type (ENKTL); mature (peripheral) T cell lymphoma(PTCL), including PTCL-not otherwise specified (NOS), angioimmunoblastic T cell lymphoma (AITL), and anaplastic large cell lymphoma (ALCL); and precursor T lymphoblastic lymphoma/leukemia (T-LBL) (Supplementary Figure 2). Here, MALAT1 is linked to mature T-cell and NK-cell non-Hodgkin lymphoma.
